LOOM TEMPLE.

Application filed August 10, 1927.

This invention relates to improvements in loom temples, and the principal object of the invention is to provide a temple of improved form and having certain novel and highly advantageous structural features as hereinafter set forth.

A specific object of the invention is to provide a temple of the chain type which shall be more efficient by reason of a novel arrangement of the cloth-penetrating pins which are confined entirely to the selvage in such manner as to hold the material without tearing or cutting the yarns, against the tremendous strains to which the fabric is subjected by the action of the temple.

Another specific object of the invention is to provide a chain temple in which special provision is made for facilitating the operation of entering the cloth. and to this end the invention contemplates the provision of a cloth guide and guard which shall be ad justable from its normal position in close proximity to the chain pins to a retracted position affording free access to said pins, all as hereinafter clearly set forth.

A still further object of the invention is to provide a temple in which the cloth-engaging elements are adiustable transversely of the loom to afford the desired degree of stretch and to relieve the stretch in the event that circumstances, such for example as an imperfection in the cloth. require that the latter be temporarily released from the temple in order that the filling be picked out of the woven fabric to a point where the imperfection originated. This device materially facilitates placing or replacing the cloth on the pins of the chain.

The invention further contemplates provision in a temple of the type set forth of means for preventing damage to the reed or temple in the event of the shuttle coming to rest between the reed and the temple due to accident such as breakafie in some part of the picking motion, and to this end proviin accordance with my invention;

Serial No. 212,011.

Fig. 2 is a section on the line 2-2, Fig. 1:

Fig. 3 is an enlarged plan view of one of the temple heads and associated parts, the

upper guard plate'of the said head being removed;

Fig. 4 is a front elevation of the parts shown in Fig. 3 but with the said guard plate in position;

Fig. 5 is an end elevation of the parts shown in Fig. 4;

Fig. 6 is a. section on the line 66, Fig. 3, and

Fig. 7 is a view in perspective of one of the links of the temple chain.

With reference to the drawings, 1 designates the breast beam of the loom over which passes the Woven fabric, 2, shown in broken lines. in the usual manner. To the inner face of the breast beam 1 and at opposite ends thereof are secured in the present instance a pair of brackets 3 to each of which is pivotally secured one end of an outwardly extending horizontal flat rod 4 which in each instance constitutes the support for a temple head 5. In each instance, the outer end of the flat rod 4 rests in back of a stop 6 on a second bracket 7 also secured to the inner face of the breast beam, and a spring 8 secured to the bracket 3 engages an edge of the rod 4 and resiliently holds it against the said stop. In each instance, the arrangement is such that the rod 4 is permitted movement around its pivot outwardly towards the breast beam and in opposition to the tension of the spring 8.

The temple head in each instance consists of a body or base plate 9 which rests upon the upper face of its supporting rod 4 and has secured to its under side a part 10 which closely embraces and surrounds the rod 4 in such manner as to hold the base plate 9 firmly in position against the upper face of the rod, while at the same time permitting longitudinal movement of the headon the rod. On that end of the base plate which lies nearest the center of the loom are rotatably mounted a pair of wheels 11., these wheels lying flat against the upper face of the base plate. freel rotatable, is adapted to travel a chain 12 composed of a series of links. one of which is illustrated in perspective in Fig. 7

These links 13 are therein shown flat at both top and bottom and have at one end Around. these wheels 11, which are a horizontal lug 14 )lOVldGd with a vertical pinhole 15 and at tie opposite end a horizontal groove 16 adapted for reception of the lug 14 of the adjacent link and having in this part a pinhole 17 so positioned as to register with the hole 15 of the inserted lug 14 to provide for the insertion of a pin 18 by means of which the links are pivotally secured together. The inner faces of the links which abut the peripheries of the wheels 11 are flat and perpendicular, as well illustrated in Fig. 6, and as therein also clearly shown, the outer faces of the links are inclined to the perpendicular slanting inwardly at the top, and these slanting or beveled outer faces are provided in a preferred form with two horizontal and spaced rows 1 and 20 of fabric-retaining pins which function as hereinafter set forth.

Adjacent the outer run of the chain 12 is an upright guide and guard plate 21 which is carried on a horizontal plate 22 hinged at 23 to a second plate 24 permanently secured to the upper face of the base plate 9, this hinged connection of the plate 22 to the base permitting its being turned back, as indicated in brokenlines in Fig. 4;, thereby affording free access to the temple chain for a purpose hereinafter set forth. In order to normally retain the guide and guard plate 21 and its supporting plate 22 in the operative position as shown in Fig. 3, I provide upon the plate 24 a pivoted latch 25 adjustable to a position overlying the plate 22 whereby the plate is held in the operative position, this latch, however, being freely adjustable by turning to an inoperative position permitting the turning back of the plate 22, as previously described.

It should be noted that the temple heads are each provided at their outer ends with a set screw 26 by means of which the head may be anchored to the supporting rod 4 and which also provides when released for adjusting the temple head on the rod. It will also be noted that the head is provided in that part occupied by the chain with a cover plate 27 which is secured to the base in the present instance by means of screws 28 which enter the upwardly projecting pins 29 constituting the axes of the wheels 11, which cover platestops short at the outer sides to provide a slot 30 between itself and the guide 21 throughwhich the edge of the fabric, as hereinafter more fully described, has access to the outer run of the chain. The guide plate 27 functions not only to prevent the fabric 2 coming into contact with the moving parts of the temple, but also to retain the wheels 11 in position.

Means is provided for adjusting the temple heads longitudinally on their respective rods, this means constituting in each instance a rod-embracing plate 31 detachably secured to the rod by means of a set screw 32 and having journaled in a projecting lug 33 thereof a threaded shaft or bolt 3% which may be rotated by means of a wing nut 35 at its outer end and whose threaded inner end is engaged in a correspondingly threaded opening in a lug 36 projecting from the temple head. Axial movement of the rod in the lug 33 is prevented in one direction by a shoulder 37 and in the other direction by a collar 38 secured to the shaft by means in the present instance of a set screw 39. By turning the shaft 3-l through the medium of the nut 35, it is obvious that the entire temple head may be adjusted longitudinally of its supporting rod 4, and adjustment of the entire device in accordance with the width of the fabric may also he made by releasing the set screw 32.

The operation of the device is as follows: In applying the fabric to the temples, the temple heads are adjusted inwardly towards the center of the loom so that the edges of the fabric may be passed downwardly over the outer runs of the chains without undue stretching. Application of the fabric is greatly facilitated by the ability to turn back the guide plate 21, this plate when turned back as described affording free access to the outer run of the chain. The

edges of the fabric then are passed down wardly over the outer run and the selvaged edges are pierced by the two rows of pins 19 and 20, after which the guide and guard plate 21 is returned to the normal operative position, as shown in Fig. 3, and is therein retained by the latch 25. It will be apparcut that by utilizing the two separate rows 19 and 20 of the fabric-retaining pins, 0, much firmer grip is retained than by use of the usual single row, and I have found in practice that this materially strengthens the grip of the temple on the fabric and eliminates any tendency of the fabric to tear loose from the pins. It will benoted particularly that the fabric in moving comes in contact only with the coverplate 27, the guide plate 21 and the outer faces and pins of the temple chain 12. The inclined faces of the chain links as described provide for a firm grip of the pins on the fabric without undue friction between the fabric and the temple parts with which it comes in contact. Following the application of the selvaged edges of the fabric to the chain and the adjustment of the plate 22, the temple heads are adjusted outward ly by means of the bolts 34, as described above, until the desired tension and degree of stretch is placed upon. the fabric. The fabric is now drawn over the breast beam in the usual manner, and as itadvanccs, the chain 12 freely rotates and continuously holds the fabric in the desirable condition.

It will be noted that the line passing through the axes of the wheels 11 is slightl inclined to the direction of movement of the fabric, the chain at the point where the fabric initially comes into contact with it being slightly further from the center of the loom than where the fabric leaves the chain. This inclination automatically relieves the strain on the fabric and permits a gradual and normal contraction of the cloth.

A material advantage results from the mounting of the temples on the pivoted fiat rods 4 which are normally resiliently held in an advanced normal position but which are freely movable outwardly to a certain extent in the event of undue pressure being applied to their inner faces, as in the event of the shuttle coming to rest between the tem 1e and reed. In this instance, the forward movement of the lay bringing the shuttle into contact with the temple parts will merely cause a pivotal movement of the supporting rods around their pivots and will thereby avoid breakage of the parts.

It will be understood that there may be some modification of the device, as herein illustrated, without departure from the essential features of the invention.

I claim:

1. In a loom tem Ie, the combination with a support adapt to be mounted transversely of the loom, of a bracket member mounted on and adjustable longitudinally of the support, a pair of pivot members projecting upwardly from said bracket, wheels rotatable on said pivots, a chain operative on said wheels and having links provided with projecting fabric-retaining elements, and a cover plate for said wheels secured in position overlying the said wheels by means of screws threaded into the tops of said pivot members.

2. In a loom temple, the combination with a support adapted to be mounted transversely of the loom and having pivotal movement in a substantially horizontal plane, of a bracket member carried by and longitudinally adjustable on said support, a pair of wheels mounted for rotation on said bracket, a chain operative on said wheels and having links provided with projecting fabric-retaining elements, a cover plate carried by said bracket and overlying said wheels, a guard element arranged closely adjacent one side of the chain and hinged to the bracket whereby the guard may be turned back to afford free access to the chain, a latch adapted normally to positively lock the guard in operative position, resilient means normally retaining the said support in a predetermined operative posi tion, and a bracket-adjusting member relatively fixed with respect to the said support and operatively engaging the bracket and providing means both for adjusting the bracket longitudinally of the support and for retaining the bracket in the adjusted position, and means independent of said adjusting means for locking the bracket on the support.
